Ende der Bekenntnisschulen?

SIEGBURG. (hpd) Die Grünen in NRW haben am Wochenende auf ihrem Landesparteitag in Siegburg beschlossen, die Bekenntnisschulen in Gemeinschaftsschulen umzuwandeln. Ohne Gegenstimmen und bei nur wenigen Enthaltungen hat die Regierungspartei damit den Weg frei gemacht für eine Änderung der nordrhein-westfälischen Schullandschaft.

Grüne gegen strikte Trennung von Kirche und Staat

Die Grünen-Politiker Sven Giegold und Winfried Kretschmann haben sich in einem parteiinternen Thesenpapier gegen einen Laizismus ausgesprochen. Damit stellen sie sich gegen Teile ihrer eigenen Partei.

Eine striktere Trennung von Kirche und Staat führe zu einem Gesellschaftsbild, das nur noch den Staat und den einzelnen Bürger kenne. Dabei bleibe der Zusammenhalt in der Gesellschaft auf der Strecke, heißt es in dem Papier des baden-württembergischen Ministerpräsidenten Kretschmann und des Europa-Abgeordneten Giegold. Der Staat profitiere von Glaubensgemeinschaften, weil sie die Gemeinschaft förderten. „Die Religionsgemeinschaften bilden Werte aus, die die Bürger_innen in das Gemeinwohl einbringen, sie bilden Sozialformen und Organisationen aus, in denen diese gelebt werden können, und sie können dadurch auch zum kritischen Korrektiv für den Staat selbst werden“, formulieren die Grünen-Politiker in dem Papier. Entsprechend solle der Staat religiöse Gruppen, auch muslimische, fördern und sich einem Laizismus entgegenstellen.

„Is Spacetime a Fluid?“ Leading Physicists Query

What if spacetime were a kind of fluid? This is the question tackled by theoretical physicists working on quantum gravity by creating models attempting to reconcile gravity and quantum mechanics. Some of these models predict that spacetime at the Planck scale (10-33cm) is no longer continuous – as held by classical physics – but discrete in nature. Just like the solids or fluids we come into contact with every day, which can be seen as made up of atoms and molecules when observed at sufficient resolution. A structure of this kind generally implies, at very high energies, violations of Einstein’s special relativity (a integral part of general relativity).

In this theoretical framework, it has been suggested that spacetime should be treated as a fluid. In this sense, general relativity would be the analogue to fluid hydrodynamics, which describes the behaviour of fluids at a macroscopic level but tells us nothing about the atoms/molecules that compose them. Likewise, according to some models, general relativity says nothing about the „atoms“ that make up spacetime but describes the dynamics of spacetime as if it were a „classical“ object. Spacetime would therefore be a phenomenon „emerging“ from more fundamental constituents, just as water is what we perceive of the mass of H2O molecules that form it.Stefano Liberati, professor at the International School for Advanced Studies (SISSA) in Trieste, and Luca Maccione, a research scientist at the Ludwig-Maximilian University in Munich, have devised innovative ways of using the tolls of elementary particle physics and high energy astrophysics to describe the effects that should be observed if spacetime were a fluid. Liberati and Maccione also proposed the first observational tests of these phenomena. Their paper has just been published in the journal Physical Review Letters.

Observation of Big Bang Gravity-Waves Challenged –„Serious Flaws Found“

Astrophysicists are casting doubt on what just recently was deemed a breakthrough in confirming how the universe was born: the observation of gravitational waves that apparently rippled through space right after the Big Bang. If proven to be correctly identified, these waves — predicted in Albert Einstein’s theory of relativity — would confirm the rapid and violent growth spurt of the universe in the first fraction of a second marking its existence, 13.8 billion years ago.

The apparent first direct evidence of such so-called cosmic inflation — a theory that the universe expanded by 100 trillion trillion times in barely the blink of an eye — made with the help of a telescope called BICEP2, stationed at the South Pole, was announced in March by experts at the Harvard-Smithsonian Center for Astrophysics. The telescope targeted a specific area known as the „Southern Hole“ outside the galaxy where there is little dust or extra galactic material to interfere with what humans could see.“Detecting this signal is one of the most important goals in cosmology today,“ John Kovac, leader of the BICEP2 collaboration at the Harvard-Smithsonian Center for Astrophysics, said at the time. By observing the cosmic microwave background, or a faint glow left over from the Big Bang, the scientists said small fluctuations gave them new clues about the conditions in the early universe.

The gravitational waves rippled through the universe 380,000 years after the Big Bang, and these images were captured by the telescope, they claimed. If confirmed by other experts, some said the work could be a contender for the Nobel Prize.But not everyone is convinced of the findings, with skepticism surfacing recently on blogs and scientific US journals such as Science and New Scientist.

Paul Steinhardt, director of Princeton University’s Center for Theoretical Science, addressed the issue in the prestigious British journal Nature in early June. „Serious flaws in the analysis have been revealed that transform the sure detection into no detection,“ Steinhardt wrote, citing an independent analysis of the BICEP2 findings.
